Key value for chemical safety assessment
Additional information
Data on the acute toxicity of Fatty acids, C16-18 and C18-unsatd., ethyl esters (CAS 85049-36-1) to fish is not available. The assessment was therefore based on a study conducted with the structurally similar substance Isopropyl oleate (CAS 112-11-8) as part of a read across approach, which is in accordance with Regulation (EC) No. 1907/2006, Annex XI, 1.5. Further justification is given within the overall summary chapter 6.1 and within the analogue justification section 13.
The available study on Isopropyl oleate (CAS 112-11-8) was conducted as a limit test according to OECD guideline 203 (Bogers, 1997). The test was performed in a static system, using Cyprinus carpio as test organism. The fish were exposed to a nominal test concentration of 100 mg/L. The test solution was prepared with acetone as a pre-solvent. No mortalities were observed at any of the test concentrations, during the 96-hour test period. A LC50 (96h) > 100mg/l was reported. Thus, no toxicological effects on fish are expected up to the limit of water solubility for Fatty acids, C16-18 and C18-unsatd., ethyl esters (CAS 85049-36-1). The result is supported by a test performed by Loeb and Kelly (1963). In the static test Cyprinus carpio were exposed to the substance for 70 hours. A LC0 >= 118 mg/kg bdwt. based on mortality was observed.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
